We are similar. I've had 4 c/s in 4years. My kids ages now are 5,4,3, 1 1/2 and we are pregnant with our 5th that will be delivered via c/s. I would just talk with your doc though. Everyone is different. Mine takes each delivery by itself to see if we should have more kids. So far he's never said not too.

I am having my 6th c-section in January.
After #5 I asked my dr his thoughts on more children and he said he saw no reason why I couldn't.
With #3 I did have some scar tissue they had to deal with but it wasn't major and haven't had it again.
I think it is a very personal decision. My dr once talked to me about risks and he said that yes while the risks increase after 3 they are not incredibly high.
My pregnancy has gone very well this time. There are moments I worry but I try not to scare myself.
Good luck toyou in your decision
